Colin and Ewan McGreggor explore the history of the Battle of Britain.

Brothers Colin and Ewan McGregor follow up their documentary The Battle of Britain with a film exploring Bomber Command, a rarely-told story from the Second World War. The film focuses primarily on the men who fought and died in the skies above occupied Europe, with numerous examples of individual heroism and extraordinary collective spirit, and Colin learns to fly the key aircraft of the campaign: the Lancaster bomber. But this is also the story of a controversy that has lasted almost 70 years. The programme covers six years of wartime operations, and traces the obstacles and challenges that were overcome as the RAF developed and deployed the awesome fighting force that was Bomber Command.

To celebrate the centenary of the Royal Air Force, actor Ewan and former RAF pilot Colin McGregor, his brother, take to the skies in some of the world's most iconic planes. It will quite an adventure as the brothers experience aerial combat at every stage of the RAF's story, from the dawn of the dogfight in World War One, the triumph of the 「The Few」 and the bravery of the 「Bomber Boys」 in World War Two, through to the Cold War and right up to the supersonic jets of today. On the way they will meet some extraordinary men and women, they will explore the great moments such as The Battle of Britain and The Berlin Airlift, and will uncover little known stories of bravery and brilliance. It is a story of amazing machines and epic battles but above all it is the story of the men and women whose courage and ingenuity have been at the heart of the RAF for 100 years.
